1, qaab dhismeedka bamka iftiinka meel bannaan

Laysarka hore ee fiber-ka ayaa inta badan la isticmaalay wax soo saarka bamka indhaha,leysarkawax-soo-saarka, awoodda wax-soo-saarkeedu waa mid hooseeya, si dhaqso loogu hagaajiyo awoodda wax-soo-saarka laser-ka fiber-ka muddo gaaban gudaheed waxaa jira dhib badan.Sannadkii 1999-kii, awoodda wax soo saarka ee cilmi-baarista laser fiber-ka iyo horumarinta ayaa jebisay 10,000 watts markii ugu horeysay, qaab dhismeedka laser fiber inta badan waa isticmaalka bamgareynta laba-geesoodka ah, sameynta resonator, iyadoo la baarayo waxtarka qulqulka fiber-ka. laser wuxuu gaadhay 58.3%.
Si kastaba ha ahaatee, in kasta oo isticmaalka iftiinka bamka fiber-ka iyo tikniyoolajiyadda isku xirka laysarka si loo horumariyo laser-ka fiber-ka ayaa si wax ku ool ah u wanaajin kara awoodda wax-soo-saarka ee leysarka fiber-ka, laakiin isla mar ahaantaana waxaa jira kakanaanta, taas oo aan ku habboonayn muraayadda indhaha si loo dhiso waddada indhaha. mar laser u baahan yahay in la dhaqaajiyo in geeddi-socodka dhismaha jidka indhaha, ka dibna jidka indhaha ayaa sidoo kale u baahan in dib-u-hagaajin, taas oo xaddidaysa codsiga ballaaran ee qaab-dhismeedka bamka indhaha fiber lasers.

2, qaabdhismeedka oscillator toos ah iyo qaabdhismeedka MOPA

Iyada oo la horumarinayo laser-ka fiber-ka, xayndaabyada korantada ayaa si tartiib tartiib ah u beddelay qaybaha muraayadaha, fududaynta tallaabooyinka horumarinta ee laser-ka fiber-ka iyo si aan toos ahayn hagaajinta waxtarka dayactirka ee laser-ka fiber-ka.Isbeddelkan horumarineed wuxuu calaamad u yahay waxtarka tartiib tartiib ah ee laser-ka fiber-ka.Qaab dhismeedka oscillator-ka tooska ah iyo qaab-dhismeedka MOPA waa labada qaab-dhismeedka ugu caansan ee leysarka fiber-ka ee suuqa.Qaab dhismeedka oscillator-ka tooska ah ayaa ah in shabaggu uu doorto hirarka dhererka geeddi-socodka oscillator-ka, ka dibna uu soo saaro mawjadda la doortay, halka MOPA ay u adeegsato mawjadda dhererka ay dooratay shabaggeedii sida iftiinka abuurka, iftiinka abuurkana waxaa lagu xoojiyaa ficilka ugu horreeya. amplifier-heer, sidaas darteed awoodda wax soo saarka ee laser fiber ayaa sidoo kale la wanaajin doonaa ilaa xad.Muddo dheer, laysarka fiber-ka leh qaab-dhismeedka MPOA ayaa loo isticmaalay qaab-dhismeedka la doorbiday ee leysarka fiber-ka sare ah.Si kastaba ha ahaatee, cilmi-baarisyada soo socda ayaa ogaaday in wax-soo-saarka awoodda sare ee qaab-dhismeedkani uu fudud yahay in uu keeno xasillooni-darrada qaybinta qaybaha gudaha gudaha laser-ka fiber-ka, iyo iftiinka laser-ka soo-saarka ayaa saameyn doona ilaa xad, kaas oo sidoo kale saameyn toos ah leh. Saamaynta wax-soo-saarka awoodda-sare.

Iyadoo horumarinta tignoolajiyada bamgareynta

Mawjadaha bamgareynta ee laser-ka hore ee ytterbium-doped fiber laser caadi ahaan waa 915nm ama 975nm, laakiin labadan mawjadaha bamgareynta ayaa ah kuwa ugu sarreeya nuugista ion ytterbium, sidaas darteed waxaa loo yaqaan bamgareynta tooska ah, bamgareynta tooska ah si weyn looma isticmaalin sababtoo ah khasaaraha tirada.In-band tignoolajiyada bamgareynta waa fidinta tignoolajiyada bamgareynta tooska ah, kaas oo dhererka hirarka u dhexeeya mawjadaha bamgareynta iyo hirarka gudbinta ay la mid tahay, iyo heerka khasaaraha quantum ee bamgareynta bamgareynta ayaa ka yar kan bamgareynta tooska ah.

Laysarka fiber awood sareciribtirka horumarinta tignoolajiyada

Inkasta oo laser-ka fiber-ku leeyahay qiimaha codsiga sare ee militariga, caafimaadka iyo warshadaha kale, Shiinaha ayaa kor u qaaday codsiga ballaaran ee laser-ka fiber-ka iyada oo loo marayo ku dhawaad ​​​​30 sano oo cilmi-baaris iyo horumarin tignoolajiyadeed, laakiin haddii aad rabto inaad sameyso laser fiber-ka ayaa soo saari kara awood sare, wali waxaa jira. carqalado badan oo ku jira tignoolajiyada jira.Tusaale ahaan, haddii awoodda wax-soo-saarka ee laser-ka fiber-ku uu gaari karo hal-qaab-fiber-hal-hab 36.6KW;Saamaynta awoodda bamgareynta ee awoodda wax soo saarka laser fiber;Saamaynta muraayadda kulaylka ee saamaynta ku leh awoodda wax soo saarka ee laser fiber.

Intaa waxaa dheer, cilmi-baarista tikniyoolajiyadda wax-soo-saarka awoodda sare ee laser fiber waa inay sidoo kale tixgelisaa xasilloonida habka transverse iyo saamaynta madow ee photon.Marka la eego baaritaanka, waxaa cad in qodobka saameynta xasilooni darada qaabka transverse ay tahay kuleylka fiber, iyo saameynta madow ee photon inta badan waxaa loola jeedaa marka laser fiber si joogto ah u soo saaro boqolaal watts ama dhowr kilowatts oo awood ah, awoodda wax soo saarku waxay muujin doontaa a hoos u dhaca degdega ah, waxaana jira xad gaar ah oo ku saabsan soo saarista awoodda sare ee joogtada ah ee laser fiber-ka.

Inkasta oo sababaha gaarka ah ee saamaynta madow ee photon aan si cad loo qeexin hadda, dadka intooda badani waxay aaminsan yihiin in xarunta cilladda ogsijiinta iyo nuugista lacag bixinta ay u horseedi karto inay dhacdo saamaynta madow ee photon.Labadan arrimood, siyaabaha soo socda ayaa loo soo jeediyay si loo joojiyo saamaynta madow ee photon.Sida aluminium, fosfooraska, iwm., si looga fogaado nuugista wareejinta lacag-bixinta, ka dibna fibbarka firfircoon ee la hagaajiyay ayaa la tijaabiyaa oo la dabaqaa, heerka gaarka ah waa in la ilaaliyo wax soo saarka korantada 3KW dhowr saacadood lana ilaaliyo soosaarka tamarta 1KW ee deggan 100 saacadood.
